driving wheel:

Application nleafreii iiar 2t} 1926, Serial This invention relates to an improved I Driving wheels arealready known where in the rims are mounted so as to be un1-- versally movable about a hub on ashaftto I provide an elastic energy "tI'QIISIIllSSlOIL.

rrccording to the present invention in a wheel of this type the connection between located in the rim of. the wheel.

' right, and

' the rim of the wheel and the, spherically.

formed hub is effected by'driving pins whic are fixed in the hub and engage in slots The construction may inithis way be cf fected in a very simple and cheap. form; Using this form ofconstructionj the rim is .freely movable on the sphe'rical-ly shaped hub and also the smallest forces set up are effective. The slots in which the driving pins engage .receive resilient me'anstrans mitting the forces fromthe rim to the hub so that the resilient means are'completely protected against temperature effects and to receive lubricating material adapted to feed the sliding surfaces of the wheel'rim and hub. The slidingsurfaces may also be" specially protected by caps of leather orthe like.

The, subject of the invention isshown in drawings, in whichr a v Figure 1 is a section through the driving wheel together with the hub casing. Figure 2 is a plan view of Figure 1. a v Figure 3 is an elevation in which the driving shaft has been turnedftoward the Figure 4 an elevation in which the driving shaft has been turned towardsthe left.

The hub casing b is tightly secured on the shaft a by means of the-bolts c. Tl1e'cas-. ing has a spherical upper surface cl against which bearsth-e correspondingly shaped rim of the driving wheel 6. The rim and the hub are connected by driving pins 9 located on the hub and engaging in slitsh which are formed between a cut away portion of the lower side of the rim of'the wheel and the hub. Inthisfiway universal movementof the rim relatively to'the hub is possible; Figures ,3 and 4: show two different positions of the driving wheel on the hub.

Springs, rubber buffers or the like k are arranged in front and to the rear of the p Ii'BClZlQIlS ,of rotation of sald members about pins 9 in the slots It, so that the springs driving wheel on, the hub is rendered posof said hub member ancljslotted, and a; pin; mountedfin saidhub'member a'ndprojectingi75' motion in any- ['direction. 2.
